S/2003 (130) 1
     W. J. Merline, Southwest Research Institute (SwRI); P. M.
Tamblyn, Binary Astronomy, Golden, CO, and SwRI; C. Dumas, Jet
Propulsion Laboratory; L. M. Close, University of Arizona; C. R.
Chapman, SwRI; and F. Menard, Observatoire de Grenoble, report the
discovery on Aug. 15.6 UT of a satellite of minor planet (130)
Elektra from K'- and H-band imaging with the 10-m Keck II Telescope
(+ NIRC2/AO adaptive optics system) on Mauna Kea.  On Aug. 15.6417,
the satellite was at separation 0".72 (projected separation 1170
km) and position angle 70 deg.  The satellite was confirmed by the
same team, also at Keck II, on Aug. 17.6.  The K'-band brightness
difference is about 8.5 mag, giving an estimated diameter of the
satellite of about 4 km.


SUPERNOVA 2003hd IN MCG -04-5-10
     M. Hamuy, N. Morrell, and J. Thomas-Osip, Carnegie
Observatories, report that a spectrum (range 360-900 nm) of SN
2003hd (cf. IAUC 8179), obtained on Aug. 15.28 UT with the Las
Campanas Clay 6.5-m telescope (+ LDSS-2), shows it to be a young
type-II supernova with a blue continuum having incipient H_alpha
and H_beta broad P-Cyg lines.
